AUTOMATIC FEED-WATER REGULATOR FOR STEAM-BOILERS.

SPECIFICATION forming part of Letters Patent No. 609,544, dated August23, 1898. Application led December 18, 1897. Serial No. 662,423. (Nomodel.)

To @ZZ wil/m it may concern:

Be it known that I, PRESTON ON EAL l-Irrr, a citizen of theUnitedStates, residing atWarren, in the county of Bradley and State ofArkansas, have invented certain new and useful Improvements in AutomaticFeed-W`ater` Regulators for Steam-Boilers; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention is a device for keeping a steam-boiler automaticallysupplied with water; and it consists of a steam ball-float valve havingan arresting-arm in combination with a steam-pump and is described asfollows:

Figure lis a longitudinal sectional view of a steam-boiler, showing anend view of my ballfloat valve and arresting-arm in position. Fig. 2 isan end view of a steam-boiler with the head cut away, showing the boilerin perspective and in position, also showing an end view of thesteam-pump and its connections with the valve and boiler. Fig. 3 is alongitudinal sectional view of my valve, and an arrestingarm, with thelever and handle of the valve removed. Fig. 4 is a transverse sectionalview of the valve on the line ce 0J, Fig. 3.

. 1 is the steam-boiler.

2 is the dome.

3 is the valve.

4 is the lever.

5 is the balliioat.

6 is the pipe leading from the valve 3 to the pipe 7.

7 is a pipe leading from pipe 6, conveying steam from valve 3 throughpipe G into cylinder 8 of the steam-pump 9.

10 is a pipe which conveys the water from the water-reservoir 1l intothe boiler 1.

The valve 3 consists of ahollow cylinder 12, provided with a steam-inlet13 and with packing-heads 15 and 16. 12 is a shaft 17, having at itsmiddle portion an enlargement 18. This shaft is hollow from point 19 toits left-hand end 14. Said enlargement 18 has an opening 20, concentricwith and corresponding to opening 13, said opening opening onto thehollow part of shaft 17. On the end 21 of shaft 17 is rigidly secured alever 4, and on the free end of said lever is secured a hollowball-float 5.

The dotted line 22 represents the low-water mark in the boiler, anddotted line 23 rep- Fitting in this cylinder resents higlrwater mark,and the valve 3 is so set that when the Wateriin the boiler is soexhausted as to be down to the low-water mark the openings 13 2O areopened and the steam passes through said openings and opening 14, thencethrough pipes 6 and 7 into cylinder 8, and operates the steam-pump 9 andforces the water from reservoir 1l through pipe 10 into the boiler belowlow-water mark. When the water rises to high-water mark, the opening 13is closed by the turning of the shaft 17, preventing the further escapeof steam, and the pump remains idle until the water becomes sufcientlylow in the boiler to open the passages 13 2O 14 for the steam to againenter the pump.

24 is an arresting-arm secured to the packing-head and situated toarrest the downward movement of the lever 4 and prevent it from fallinglow enough to cut off the steam from the openings 13 2O should the waterget lower than the low-water mark 22.

Thus it will be seen that with my device a steam-boiler may be fedautomatically and kept at all times with a sufiicient amount of Water inthe boiler.

Having described my.. invention, whati I claim as new, and desire tosecure by Letters Patent, is

The combination of the steam-boilerl; the valve 3, secured on the insideof said boiler and consisting of the hollow cylinder 12, provided with asteam-inlet 13,',and packingheads 15 16; shaft 17, provided with anenlargement, 13, and working on the inside of cylinder 12, said shaftbeing hollow from point 19 toits end 14, and having an opening 20,corresponding to opening 13 passing into the hollow of said shaft 17 5lever 4, rigidly secured to said shaft 17 and its end 21; hollow ball 5,secured on the free end of lever 4; arresting-arm 24 secured topacking-head 15; pipe 6, one end secured to the end 14 of valve 3, andpassing thence through boiler l, and adapted to convey steam to asteam-pump, 9, substantially as shown and described and for the purposesset forth;

In testimony whereof I aflix my signature in presence of two witnesses.
